Stanozolol is a synthetic anabolic steroid derived from the male hormone dihydrotestosterone (DHT) and is most commonly marketed under the brand name “Winstrol.” It is available in both oral tablet and intramuscular injection formulations. Used for building lean dry muscles, it does not aromatize in to estrogen
Due to its structural modification (the addition of a C17α-methyl group), stanozolol is orally active but also carries a higher risk for liver toxicity. It has been used in both human and veterinary medicine for its anabolic (muscle-building) properties as well as for other medical indications.
